Q. Consider an electron in the $n$th orbit of a hydrogen atom in the Bohr model. The circumference of the orbit can be expressed in terms of the de-Broglie wavelength $\lambda$ of that electron as
A) $(0.529)\ n\lambda$
B) $\sqrt{n}\ \lambda$
C) $(13.6)\lambda$
D) $n\lambda$
Explanation
(d) Circumference of $n$th Bohr orbit $= n\ \lambda$
